TOP-ROLLER CLEAREB.

Application filed May 6,

To all whom it may concern:

Be it known that we, Mann SUTTON and THOMAS VVrLLIniirs, both British subjects, residing both at Rio de Janeiro, Brazil, South America, have invented certain new and useful Improvements in Top-Roller Clearers, of which the following is a specification.

This invention relates to clearers for the top rollers of spinning frames, spinning mules, preparation machines, drawing frames, and other machines for the treatment of cotton, flax, wool and other fibres.

A conical travelling clearer resting upon the two front top rollers of such machines is well known and this invention comprises the combination with a conical travelling clearer of an auxiliary clearer of flat or curved shape to travel with the conical roller and engage or rest upon the other rollers and thus ensure that all the top rollers are more effectively cleaned and kept clear of fluff or loose fibres.

The invention will be fully described with reference to the accompanying drawings.

Fig. 1 is an end view of the improved combination clearer in its working position.

Fig. 2 is a front view of the combination clearer.

Fig. 3 is a plan view of the same.

The rollers may be of the ordinary arrangement for any of the before mentioned machines those shown as an example being for a spinning frame with three lines of top rollers but it is to be understood that the invention is applicable to machines with any number of lines of top rollers the auxiliary clearer A being shaped to suit.

The combination clearer is constructed with a plate A which may be flat or curved to the contour of the rollers formed with an opening C, into which a conical roller B is fitted. The plate A may be of wood or metal preferably sheet iron and is covered on its under surface with a covering a of flannel or other suitable fabric. On its upper surface adjustable bearing brackets D are bolted. against which the journals 6 of the conical clearer roller B rest and which facilitate the setting of the conical clearer to control the amount of friction between it and the top rollers, and thereby determine the rate oftraverse of the combination clearer.

1922. Serial No. 558,991.

The conical roller clearer B may be set to operate in contact with the front and middle top rollers or it may be applied to any other pair of top rollers.

The auxiliary clearer or plate A may first be placed in position on the top rollers. and the conical clearer roller B be then placed in position through the opening 0 with the journals Z) resting against the bearing brackets D When working the conical clearer roller B being in contact with the revolving top rollers is caused to rotate and by reason of its conical form, it travels longitudinally along the top rollers in that direction in which the small end of the cone is leading. This longitudinal travel of the conical clearer roller carries the auxiliary clearer A. forward at the same time, the result being, that the top rollers are most effectively cleaned, first by the auxiliary clearer and then by the conical clearer itself.

The clearer may be caused to travel in the reverse direction by reversing the conical roller B in the opening 0.

What we claim as our invention and desire to protect by Letters Patent is z- 1. In a clearer for the top rollers of machines for treating and spinning fibres the combination with a conical traversing roller of an auxiliary clearer provided with an aperture in which the traversing roller is arranged the auxiliary clearer being flat at the front and curved at the back to fit over the top rollers to be cleaned.

2. Tn a clearer for the top rollers of machines for treating and spinning fibres the combination with a conical traversing roller of an auxiliary clearer provided with an aperture in which the traversing roller is arranged and adjustable brackets for adj usting the position of the conical traversing roller.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
